Here's a post from reddit that seems very helpful in regards to the subject of this thread:

5+ Years Free From Porn - Here's what changed me.

"I see a lot of guys on here struggling to get free from porn and fighting just to be free from their sin even for just a few days. I'd like to share my story to help change your thinking about all of this.

I'm a guy who used to struggle with pornography and masturbation as a believer for many years starting at the age of 13 up until I was about 20 years old.

After trying many times to stop by setting boundaries, removing triggers, and "trying to be holy" I still failed over and over again... until one day God began to change my thinking about how I saw myself and how He saw me. "
